Abstract

This paper presents the patent of a new additive for the construction industry, which is obtained from the biomass residues of the wood industry, this additive is biodegradable and has fluidifying, foaming, plasticizing and stabilizing properties. When the additive is mixed with cement binder compositions, cement mortar and concrete, lightweight, flame-retardant cellular materials, thermal and acoustic insulators are obtained.

This additive has its application in the production of new materials for construction (light mortars for screeds and flat roofs, lightweight concretes, prefabricated panels, light plates for false ceilings, blocks and bricks for enclosures and interior divisions, with densities that vary between the 700 - 1000 Kg/m3 and with coefficients of thermal conductivity between 0,11 - 0,34 W/mºK), characteristics that improve the energetic efficiency of the buildings.
